BRICK-SCORIN G MECHANISM.

Application filed October 9, 1916v To all whom it may concern:

Be it known that I, \VILLIAM B. RonINsoN, citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements ,in Brick-Scoring Mechanisms; and I do declare the following to be a full, clear, and exact description of the invention, such will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

The present invention relates to improvements in brick making machines and pertains more particularly to marking devices adapted to be located between the feeding machine and the cutter.

The invention has for its principal object the provision of suitable marking attachments to be used between the feeding machine and the cutter and adapted to act upon the column of clay as it is moved along on the measuring belt thereby producing designs upon the unfinished material which will appear as irregular scrolls upon two faces of the finished bricks.

A further object of the invention consists in providing marking devices of the kind referred to which will operate automatically and will in no way retard the progress of the brick making machines. The apparatus is capable of various adjustments enabling thc'operator to control the depth of the imprints or designs to be cut into the brick surfaces.

with these and other objects in view the inventioh consists in the combinatiop arrangement of parts more fully set forth in the following specification, illustrated in the accompanying drawing and more p rticularly pointed out in the appended claim.

In the drawings-:'

Figure 1 is a. front elevation of one em bodiment of the present invention, parts-being shown in section and taken on the line 11 of Fig. 3.

Fig. 2 is a side elevation showing the column of clay being fed along the measuring belt and with the marking devices operatlng thereon-.3

Fig. 3 is a horizontal sectional view taken on the line 2-2 of Fig. 1, looking in the direction of the arrows.

having two of its surfaces marked with the designs such as contemplated by the present invention, and.

Fig. 5 is a fragmental view of a wall constructed of bricks so marked.

Referring now to the drawings, the column of clay is delivered from the feeding machine 5 onto the measuring belt 6 along which it is carried to the cutter (not shown). The. marking devices forming the principal features of the present inventlon are carried on an upright postor standard 7 suitabl positioned at one side of the measuring be t 6. As shown clearly in Fig. 1 the column of clay C travels along the measurin belt resting on one of its wider edges. ing devices are provided, one operating on the upper edge or surface of the column and the other on the side thereof, consequently when the column is cut into bricks, each in dividual brick will be marked as shown in Fig. 4 with the design cut on its long narrow surface or edge and also on its small end surface.

The upper marking device is supported on the upright post or standard 7 being suspended from a bracket 8 which is slidably secured to a pair of slotted arms 9 of a supporting bracket 10 fixed to the post 7. Ad: justing bolts and nuts 11 are passed through the slotted arms 9 and thecorresponding slots 12 formed in the ears 13 of bracket 8 for the purpose of maintaining the bracket 8 in any adjusted position. The bracket plate 8 is provided with a pair of journal boxes 14 between the supporting cars 13, in which is suitably journaled a horizontally disposed driving shaft 15 carrying a pulley 16 at one end thereof which is driven from any suitable power source (not shown) by means of a belt 17. The driving shaft 15 is provided at its opposite end with a pinion 18 keyed thereto and meshing with a, gear 19 fixedly carried on the end of a stub shaft 20suported in a bearing 21 also integral with the bracket plate 8. A pair of vertically spaced bearing arms 22 are formedintegral with the bracket plate in the lower of which is.

slidably mounted a. vertical shaft 23 to the lower end of whichis secured the marking disk 24 carrying a series of vertically adjustablc,.depending spikes or markers '25. The upper end of shaft 23 is connected by means of a swivel joint :26 with the lower W0 markend of a coaxially disposed shaft 27 thrended into the upper bearing arm '22.
